structures and premises. It contains supplementary and amendatory requirements
which by their inclusion herein are adopted as requirements under Section 5 of The
Electrical Inspection Act, 1993.
Section 0:
Definitions
Section 0 is supplemented by the following:
Grade Level means the level of earth surrounding a building, and in cases where
the electrical installation is performed before the building is back-filled, shall be
considered as that level 50 mm below the basement windows, other than those in
window wells, or 150 mm below siding, or stucco line on basementless homes.
Kiosk means an enclosure of steel or a combination of masonry and steel and
which may be partly buried and within which may be installed a standard oil-filled
transformer and protective equipment.

Pad-mounted transformer means a transformer consisting of compartmented
steel enclosure with space for standard oil-filled transformer, high-voltage protective
and switching equipment and low-voltage feeder connections or distribution
transformers of special design to which compartmented enclosures can be attached, all
of such equipment designed to be mounted on a concrete or fibreglass pad of suitable
dimensions on grade.
Rural Area means an area outside of the limits of any hamlet, village, town or
city.
Service Factor means a multiplier which, when applied to the rated horsepower
of an AC motor, the rated armature current of a DC motor, or to the rated output of a
generator, indicates a permissible loading which may be carried continuously at rated
voltage and frequency.
Service Stack means that portion of service conductors including raceway,
armour or sheathing, between the point of attachment to the service supply and the
consumers service box or equivalent service equipment.
Shallow Box means an outlet box with a depth less than 1 1/2 inches and a

APPENDICES
Appendix B
2-015
Appendix note 2-015 is added pertaining to Rule 2-015.
Rule 2-015 requires that plans and specifications shall, in addition to other
details, contain the maximum short circuit current available at each point of
application of protective devices in installations exceeding 600 A. Because of
the lower impedance’s in the energy-efficient transformers currently being
used by utilities and available for customer-owner installations, the resultant
higher short circuit availability makes the requirement in this rule even
more important. For example, a 500 KVA 120/208 V transformer with 2%
impedance has a short circuit current of 69400 amp available at its
terminals (based on infinite primary) whereas one with 5% impedance
would have only 27760 amp available.
On the basis that code fuses and many circuit breakers have an interrupting
capacity rating of 10000 amps, it will be apparent from the tabulation below,
that a substantial number of systems will require careful fault current
analysis to ensure compliance with rule 14-012 and related note in
Appendix B of the Code. Whereas the short circuit current available for the
overcurrent device to interrupt is dependent upon several factors, such as
distance, type and size of circuit conductors careful attention must be given
to arrangements with a short bus between a transformer and a distribution
centre.
Review of plans not having the required short circuit current information
will be withheld until it is made available and the selected overcurrent
devices are determined to have satisfactory IC rating. If values are not
available from utilities (on rare occasions) the inspection office should be
consulted for concurrence with an estimated value.
18-405
Appendix note 18-405 is added regarding Rule 18-405
As per CSA Standard B52-M a Class T machine room requires the
following:
A Class T machinery room shall have no ignition source apparatus
permanently installed and operated and also shall conform to the
following:
a) Emergency remote controls to stop the refrigerant compressor
shall be provided and located immediately outside the machinery room;
b) An independent mechanical ventilation system conforming to
Clause 7.10.4 shall be provided for all machinery rooms. In basements and
sub/basements the ventilation system shall be operated continuously. In all
other locations the machinery rooms shall have continuous ventilation or be
equipped with a gas-monitoring system that will automatically start up the
ventilation system and actuate a remote alarm at the lowest practical
instrument-detection level not exceeding 25% of the lower explosive limit;
41
CANADIAN ELECTRICAL CODE
(SASKATCHEWAN AMENDMENTS), 1995

c) Emergency remote controls for the mechanical means of
ventilation shall be provided and located outside the machinery room.
62-114
Appendix note 62-114 is added pertaining to subrules 62-114 (6) and (7).
With continuing increase in use of electric furnaces and the need for proper
sizing of disconnect, overcurrent protection and supply conductors, the table
thereunder has been prepared for ease of reference.

A sample selection for a 20 KW furnace follows: The ampacity of the conductors
supplying the electric furnace and the size of the overcurrent devices are determined
by applying Rule 62-114.
The overcurrent device for the furnace must be sized so that the total connected
load of the heating equipment does not exceed 80% of the rating of the overcurrent
device in accordance with subrule (6). In this case, the load is 83.3 amps, the minimum
size of overcurrent devices is 83.3 / 0.8 = 104 amperes. The next available fuse is 125
amperes.
Since this fuse is supplying a heating load, Rule 14-610 requires that the fuses be a
time delay type or HRC Form I.
The conductor size is determined by applying subrule (7) of 62-114. The conductor
must be of an ampacity sufficient to carry the load, must have an ampacity rating at
least 80% of the rating or setting of the branch circuit overcurrent device. A conductor
rated at 100 amperes, i.e. #3 AWG R90 (Column 3 of Table 2) would satisfy these
requirements.
Based on the conduit fill requirements of Rule 12-1014 and Tables 6 and 10, it can
be determined that the 2 #3 AWG R90 conductors require a 1 1/4" conduit.
The size of the conduit used for bonding equipment must be considered. Rule 10814 and Table 16 require a 1 1/2 EMT conduit where the overcurrent protection
exceeds 100 amperes.
Therefore in this installation the 1 1/4 EMT conduit would have to be increased
to 1 1/2 EMT.
